# Cactus Link

## What is Cactus Link?

Cactus Link is Cactus Custody's institutional DeFi connector, designed to bridge the gap between enterprise custody infrastructure and decentralized applications. It provides secure, controlled access to DeFi protocols while assets remain protected within Cactus Custody's institutional-grade infrastructure. Currently, Cactus Link connects custodied assets to 1,000+ DApps across 30+ blockchains.

Cactus Link is available as a Chrome browser extension. It supports EVM-compatible chains, Cosmos, Solana, and more, with wallet switching and multi-chain asset management handled from a single interface.

## How Cactus Link Works

{% stepper %}
{% step %}

### Assets Remain in Custody

All assets remain securely held by Cactus Custody within your DeFi account, and are fully segregated from the funds in your Segregate Account.
{% endstep %}

{% step %}

### Connect to DApps via Cactus Link

Users initiate and confirm DeFi transactions through the Cactus Link interface. The system generates transaction requests that route through your defined approval workflows and security controls.
{% endstep %}

{% step %}

### Custom Multi-Approver and Risk Checks

Cactus Link validates each transaction against your organization's risk policies, including contract whitelists and approval requirements. Multi-layer approval workflows ensure proper governance.
{% endstep %}

{% step %}

### Complete Audit Trail

Cactus Custody logs all actions and approvals for comprehensive audit and compliance reporting. Every DeFi interaction is recorded with full transaction details, approval history, and on-chain verification.
{% endstep %}
{% endstepper %}

## Security Controls

All DeFi transactions initiated through Cactus Link are subject to the security controls configured by your administrator in the DeFi Policy Engine. These controls define which DApps, smart contracts, addresses, and transaction types are permitted, and vary by blockchain ecosystem.

Each transaction must also pass through your organization's multi-level approval workflow before it is signed.

For full details on available controls, refer to [DeFi Policy Engine](/defi/defi-policy-engine.md).

## Getting Started

Cactus Link requires an active DeFi Account with a wallet address assigned to a Financial Manager role, and a fund password for transaction authorization.

Cactus Link can be installed from the [Chrome Web Store](https://chromewebstore.google.com/detail/cactus-link/chiilpgkfmcopocdffapngjcbggdehmj?hl=en\&pli=1).

### Cactus Link Password

Cactus Link has its own password used to login to the extension. If you forget the password, you can delete the extension, reinstall it, and reconnect. Changing the Cactus Link password will not limit operations for 24 hours.
